An old cartoon sound effect question

SFX in question: the one where something negative happens to the character:
‘Wah wah wah wah wahhhhhhhh’, where each ‘wah’ goes down a step or so in tone.
Question: Does anybody here know exactly what that sound effect is? Is it on the Hanna Barbera sfx library?
I ask, cuz a friend of mine asked me today how you would even research such a thing (difficult to put into words), and I think it’s a great question.
It’s maybe a muted trumpet, if that helps.

I love it!

I think the sometimes used ‘higher-pitch’ one is a muted trumpet… is blocked for me, so I’m not sure if this is the same one or not:

Ok, I’ve got a cartoon sound-effect question: when a person starts running, but they’re not going anywhere, there’s a crazy bongo sound - but is it really bongos?

TerpBE, yep, that’s the exact same one (also don’t forget

Daithi Lacha, if it’s this, then yeah, it sounds like regular bongos to me.

I’m not sure what it says about me that I seem to know a lot about this stuff…

You should get a book on “old time radio” (OTR) and see what they used to use to make different sounds.

Back in the heyday of radio, you could only use transcripted (recorded) things on radio for very slim reasons. This is why all shows used to have their own bandleader 'cause James Petrillo, the head of the musicians union was so strict about things.

This is why they had to do two live broadcasts of radio, one for the East/Central time and one for the California markets.

So you couldn’t use a record of a sound effect on a radio broadcast you’d have to recreate such things live in the studio or you had to re-arrange the script so you’d have the actor say “Boy it’s raining hard.” (If say you couldn’t reproduce the sound of rain)

Here’s a few classics

How about the one where someone shakes his head real fast? “Yadda yadda yadda!” I think it was usually Warner Bros. I’ve never been able to figure out what that actually is.

Go to Bearflag70’s link and I think it is OutHere1.wav.

I don’t know they did it but I always did it by…shaking my head back and forth and going “yadda-di-yadda-di yadda-di…”
